ABSTRACT

The present invention provides 6-substituted 2,3,4,5-tetrahydro-1H-benzo[d]azepines of Formula (I) as selective 5-HT2c receptor agonists for the treatment of 5-HT2c associated disorders including obesity, obsessive/compulsive disorder, depression, and anxiety, where, R6 is —NR10R11, where R10 is substituted phenylalkyl or substituted pyridylalkyl and other substituents are as defined in the specification.

The neurotransmitter serotonin (5-hydroxytryptamine, 5-HT) has a richpharmacology arising from a heterogeneous population of at least sevenreceptor classes. The serotonin 5-HT₂ class is further subdivided intoat least three subtypes, designated 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C).The 5-HT_(2C) receptor has been isolated and characterized (Julius, etal., U.S. Pat. No. 4,985,352), and transgenic mice lacking the 5-HT_(2C)receptor have been reported to exhibit seizures and an eating disorderresulting in increased consumption of food (Julius et al., U.S. Pat. No.5,698,766). The 5-HT_(2C) receptor has also been linked to various otherneurological disorders including obesity (Vickers et al.,Psychopharmacology, 167: 274-280 (2003)), hyperphagia (Tecott et al.,Nature, 374: 542-546 (1995)), obsessive compulsive disorder (Martin etal., Pharmacol. Biochem. Behav., 71: 615 (2002); Chou-Green et al.,Physiology & Behavior, 78: 641-649 (2003)), depression (Leysen, Kelder,Trends in Drug Research II, 29: 49-61 (1998)), anxiety (Curr. Opin.Invest. Drugs 2(4), p. 317 (1993)), substance abuse, sleep disorder(Frank et al., Neuropsychopharmacology 27: 869-873 (2002)), hot flashes(EP 1213017 A2), epilepsy (Upton et al., Eur. J. Pharmacol., 359: 33(1998); Fitzgerald, Ennis, Annual Reports in Medicinal Chemistry, 37:21-30 (2002)), and hypogonadism (Curr. Opin. Invest. Drugs 2(4), p. 317(1993)).

Certain substituted 2,3,4,5-tetrahydro-1H-benzo[d]azepine compounds havebeen disclosed as useful therapeutics as for example:

U.S. Pat. No. 4,265,890 describes certain substituted2,3,4,5-tetrahydro-1H-benzo[d]azepine compounds as dopaminergic receptorantagonists for use as antipsychotics and antiemetics, inter alia.

EP 0 285 287 describes certain substituted2,3,4,5-tetrahydro-1H-benzo[d]azepine compounds for use as agents totreat gastrointestinal motility disorders, inter alia.

WO 93/03015 and WO 93/04686 describe certain substituted2,3,4,5-tetrahydro-1H-benzo[d]azepine compounds as alpha-adrenergicreceptor antagonists for use as agents to treat hypertension andcardiovascular diseases in which changes in vascular resistance aredesirable, inter alia.

WO 02/074746 A1 describes certain substituted2,3,4,5-tetrahydro-1H-benzo[d]azepine compounds as 5-HT_(2C) agonistsfor the treatment of hypogonadism, obesity, hyperphagia, anxiety,depression, sleep disorder, inter alia.

WO 03/006466 A1 describes certain substituted tricyclichexahydroazepinoindole and indoline compounds as 5-HT ligands andconsequently their usefulness for treating diseases wherein modulationof 5-HT activity is desired.

WO 05/019180 describes6-(2,2,2-trifluoroethylamino)-7-chloro-2,3,4,5-tetrahydro-1H-benzo[d]azepineas a potent and selective 5-HT_(2C) agonist for the treatment ofobesity, anxiety, depression, and obsessive-compulsive disorder.

High affinity 5-HT_(2C) receptor agonists would provide usefultherapeutics for the treatment of the above mentioned 5-HT_(2C)receptor-associated disorders including obesity, hyperphagia,obsessive/compulsive disorder, depression, anxiety, substance abuse,sleep disorder, hot flashes, and hypogonadism. High affinity 5-HT_(2C)receptor agonists that are also selective for the 5-HT_(2C) receptor,would provide such therapeutic benefit without the undesirable adverseevents associated with current therapies. Achieving selectivity for the5-HT_(2C) receptor, particularly as against the 5-HT_(2A) and 5-HT_(2B)receptors, has proven difficult in designing 5-HT_(2C) agonists.5-HT_(2A) receptor agonists have been associated with problematichallucinogenic adverse events. (Nelson et al., Naunyn-Schmiedeberg'sArch. Pharm., 359: 1-6 (1999)). 5-HT_(2B) receptor agonists have beenassociated with cardiovascular related adverse events, such asvalvulopathy. (V. Setola et al., Mol. Pharmacology, 63: 1223-1229(2003), and ref. cited therein).

Previous references to substituted 2,3,4,5-tetrahydro-1H-benzo[d]azepinecompounds as potential therapeutics have predominantly recited theiruses as alpha adrenergic and/or dopaminergic modulators. Adrenergicmodulators are often associated with the treatment of cardiovasculardiseases (Frishman, Kotob, Journal of Clinical Pharmacology, 39: 7-16(1999)). Dopaminergic receptors are primary targets in the treatment ofschizophrenia and Parkinson's disease (Seeman, Van Tol, Trends inPharmacological Sciences, 15: 264-270 (1994)). It will be appreciated bythose skilled in the art that selectivity as against these and otherphysiologically important receptors will generally also be preferredcharacteristics for therapeutics for the specific treatment of 5-HT_(2C)associated disorders as described above.

Such saltsare also embodiments of this invention.

Typical inorganic acids used to form such salts include hydrochloric,hydrobromic, hydroiodic, nitric, sulfuric, phosphoric, hypophosphoric,metaphosphoric, pyrophosphoric acid, and the like. Salts derived fromorganic acids, such as aliphatic mono and dicarboxylic acids, phenylsubstituted alkanoic acids, hydroxyalkanoic and hydroxyalkandioic acids,aromatic acids, aliphatic and aromatic sulfonic acids, may also be used.Such pharmaceutically acceptable salts thus include chloride, bromide,iodide, nitrate, acetate, phenylacetate, trifluoroacetate, acrylate,ascorbate, benzoate, chlorobenzoate, dinitrobenzoate, hydroxybenzoate,methoxybenzoate, methylbenzoate, o-acetoxybenzoate, isobutyrate,phenylbutyrate, α-hydroxybutyrate, butyne-1,4-dicarboxylate,hexyne-1,4-dicarboxylate, caprate, caprylate, cinnamate, citrate,formate, fumarate, glycolate, heptanoate, hippurate, lactate, malate,maleate, hydroxymaleate, malonate, mandelate, nicotinate, isonicotinate,oxalate, phthalate, terephthalate, propiolate, propionate,phenylpropionate, salicylate, sebacate, succinate, suberate,benzenesulfonate, p-bromobenzenesulfonate, chlorobenzenesulfonate,ethylsulfonate, 2-hydroxyethylsulfonate, methylsulfonate (mesylate),naphthalene-1-sulfonate, naphthalene-2-sulfonate,naphthalene-1,5-sulfonate, p-toluenesulfonate, xylenesulfonate,tartrate, and the like.

It is well known that such compounds can form salts in various molarratios with the acid to provide, for example, the hemi-acid, mono-acid,di-acid salt, etc. Where in the salt formation procedure, the acid isadded in a specific stoichiometric ratio, unless otherwise analyzed toconfirm, the salt is presumed, but not known, to form in that molarratio. Terms such as “(acid)_(x)” are understood to mean that the molarratio of the salt formed is not known and can not be presumed, as forexample, but without limitation, (HCl)_(x) and (methanesulfonicacid)_(x).

The compounds of the present invention are relatively selective for the5-HT_(2C) receptor. The compounds of the present invention areparticularly relatively selective for the 5-HT_(2C) receptor incomparison to other 5-HT receptor subtypes and specifically the5-HT_(2A) and 5-HT_(2B) receptors. This selectivity is demonstrated inthe following agonist activity assays and receptor binding assays.

Agonist Activity Assays (G Alpha q-GTPγ[³⁵S] Binding Assays)

The 5-HT₂ receptors are functionally coupled to specific G-proteins.Agonist activation of 5-HT₂ G-protein-coupled receptors results in therelease of GDP from the α-subunit (G alpha q or G alpha i) of theG-protein and the subsequent binding of GTP. The binding of the stableanalog GTPγ[³⁵S] is an indicator of receptor activation (i.e. agonistactivity).

The G alpha q-GTPγ[³⁵S] binding assay is used to determine the in vitropotency (EC₅₀) and maximal efficacy (E_(max), normalized to the 5-HTresponse) of a test compound at the 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C)receptors. The area under the dose response curve (AUC) is alsodetermined for each receptor subtype and used to measure the testcompound's selectivity for the 5-HT_(2C) receptor over the 5-HT_(2A) and5-HT_(2B) receptors, expressed as Selectivity Ratios (AUC 2C/2A and AUC2C/2B, respectively). The Selectivity Ratios allow the assessment ofselectivity based on both potency and efficacy. A selectivity measurethat incorporates both potency and efficacy at the 5-HT_(2C) receptor,as compared to the 5-HT_(2A) and 5-HT_(2B), receptors, is consideredimportant due to the adverse events associated with 5-HT_(2A) and5-HT_(2B) agonist activity (see introduction).

Membrane Preparation: Grow AV12 cells stably transfected with the human5-HT_(2A), 5-HT_(2B), or 5-HT_(2C) receptors in suspension, harvest bycentrifugation, wash the cell pellet with phosphate buffered saline, pH7.4, pellet the cells again, remove the supernatant, freeze the cellpellet on dry ice and store at −70° C. Thaw stock cell pellet andresuspend in 50 mM Tris, pH 7.4, aliquot into 1-2 mL volumes andrefreeze at −70° C. for subsequent assays. (As is appreciated in theart, optimal cell quantities used per aliquot will vary with theindividual transfected cell line used. In one embodiment, 5-HT_(2A) and5-HT_(2C) transfected cells are typically used at about 6×10⁸ cells peraliquot, while 5-HT_(2B) cells are typically used at about 7.5×10⁸ cellsper aliquot).

On the day of assay, thaw membranes, wash the membranes with assaybuffer (50 mM Tris-HCl (pH 7.4), 10 mM MgCl₂, 100 mM NaCl, and 0.2 mMEDTA), resuspend in assay buffer and incubate for 10 min. at 37° C. tohydrolyze any residual endogenous 5-HT. Wash the membranes again withassay buffer, and resuspend in assay buffer at a concentration toprovide aliquots of about 1-4×10⁶ cell equivalents per well (typicallyabout 1-2×10⁶ cell equivalents for assays with 5-HT_(2A) or 5-HT_(2C)receptor assays, and about 3-4×10⁶ cell equivalents for assays with5-HT_(2B) receptor assays). Homogenize the cells with a tissue grinderand use the homogenate directly in the assay as described below.

G alpha q-GTPγ[³⁵S] Binding Assays: The immunoadsorption scintillationproximity assay (ISPA) of [³⁵S]-GTPγS binding to G alpha q is modifiedfrom published conditions (DeLapp et al, JPET 289 (1999) 946-955).Dissolve test compounds in DMSO and dilute in assay buffer to provide arange of concentrations to generate a concentration response curve. Inwells of a 96 well microtiter plate, mix diluted test compound, GDP (0.1μM final concentration), and [³⁵S]-GTPγS (between 0.5 and 1.0 nM finalconcentration). Add an aliquot of membranes to the incubation mixtureand mix the plates to initiate agonist stimulation of the nucleotideexchange (200 μl final volume). Incubate the microtiter plates for 30min. at room temperature. Quench the incubation with IGEPAL® CA-630detergent (0.27% final concentration). Add affinity purified polyclonalrabbit anti-G alpha q antibody (about 1-2 μg per well), and anti-rabbitIg scintillation proximity assay beads (Amersham; about 1.25 mg perwell; 300 μl final volume). Seal the plates and incubate the mixture for3 h at room temperature. Centrifuge the microtiter plates briefly topellet beads. Quantitate the GTPγ[³⁵S] binding by microtiter platescintillation spectrometry (Wallac Trilux MicroBeta™ scintillationcounter).

Data Analysis: For each concentration response curve for a test compoundat a given receptor, analyze the data with GraphPad Prism™ software(v3.02; GraphPad Software, San Diego, Calif.) running on a personalcomputer with MicroSoft Windows OS®, using nonlinear regression analysiscurve fitting to determine the EC₅₀ and E_(max) (normalized to 5-HTcontrol curves). Determine the Area Under the agonistconcentration-response Curve (AUC) with GraphPad Prism by thetrapezoidal method.

To calculate the Selectivity Ratios, first, determine the AUC for thetest compound for each receptor subtype as described above. Second,normalize the AUC's at each receptor subtype relative to the AUCdetermined for 5-HT at that receptor. The normalized AUC for a testcompound at a given receptor is therefore expressed as a percentage ofthe AUC determined for 5-HT at that receptor. For example:

${5\; {HT}_{2\; A}\mspace{14mu} {Normalized}\mspace{14mu} {AUC}} = {a = {\frac{\begin{pmatrix}{{AUC}_{{test}\mspace{14mu} {compound}}\mspace{14mu} {at}} \\{5{HT}_{2A}\mspace{14mu} {receptor}}\end{pmatrix}}{\begin{pmatrix}{{AUC}_{5\text{-}{HT}}\mspace{14mu} {at}} \\{5{HT}_{2A}\mspace{14mu} {receptor}}\end{pmatrix}} \times 100\%}}$${5{HT}_{2B}\mspace{14mu} {Normalized}\mspace{14mu} {AUC}} = {b = {\frac{\begin{pmatrix}{{AUC}_{{test}\mspace{14mu} {compound}}\mspace{14mu} {at}} \\{5{HT}_{2B}\mspace{14mu} {receptor}}\end{pmatrix}}{\begin{pmatrix}{{AUC}_{5\text{-}{HT}}\mspace{14mu} {at}} \\{5{HT}_{2B}\mspace{14mu} {recpetor}}\end{pmatrix}} \times 100\%}}$${5{HT}_{2C}\mspace{14mu} {Normalized}\mspace{14mu} {AUC}} = {c = {\frac{\begin{pmatrix}{{AUC}_{{test}\mspace{14mu} {compound}}\mspace{14mu} {at}} \\{5{HT}_{2C}\mspace{14mu} {receptor}}\end{pmatrix}}{\begin{pmatrix}{{AUC}_{5\text{-}{HT}}\mspace{14mu} {at}} \\{5{HT}_{2C}\mspace{14mu} {receptor}}\end{pmatrix}} \times 100\%}}$

Third, calculate the Selectivity Ratios for the test compound asfollows:

Selectivity Ratio for 5-HT_(2C) receptor/5-HT₂A receptor (AUC 2C/2A)=c/a

Selectivity Ratio for 5-HT_(2C) receptor/5-HT_(2B) receptor (AUC2C/2B)=c/b

For reference purposes, the AUC 2C/2A and AUC 2C/2B for 5-HT are each1.0. Likewise, the ratios for mCPP (meta-chlorophenylpiperazine) aretested and are found to be 2.1 and 2.1 respectively.

Representative compounds of the present invention are tested in the Galpha q-GTPγ[³⁵S] assays for the 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C)receptors essentially as described above and are found to be a highlypotent and selective agonists of the 5-HT_(2C) receptor, with EC₅₀'stypically less than or equal to 250 nM, and AUC 2C/2A and AUC 2C/2B 5ratios greater than 1.5. Preferred compounds are those with EC50's lessthan or equal to 100 nM, and AUC 2C/2A and AUC 2C/2B ratios greater thanor equal to 2.0. More preferred are those with EC50's less than or equalto 50 nM, and AUC 2C/2A and AUC 2C/2B ratios greater than or equal to3.0.

Ligand Binding Assays

The ligand binding affinity of the compounds of the present invention tothe 5-HT_(2C) receptor subtype is measured essentially as described byWainscott (Wainscott, et al., Journal of Pharmacology and ExperimentalTherapeutics, 276:720-727 (1996)). Data is analyzed by nonlinearregression analysis on the concentration response curves using the fourparameter logistic equation described by DeLean (DeLean, et al.,Molecular Pharmacology, 21, 5-16 (1982)). IC₅₀ values are converted toK_(i) values using the Cheng-Prusoff equation (Cheng, et al., Biochem.Pharmacol., 22, 3099-3108 (1973)).

Representative compounds of the present invention are tested essentiallyas described above and are found to have excellent affinity for the5-HT_(2C) receptor, with K_(i)'s typically less than or equal to about250 nM. Preferred compounds are those with K_(i)'s of less than or equalto about 100 nM. More preferred are those with K_(i)'s less than orequal to 50 nM.

Affinities for other receptor subtypes can readily be determined byslight modification of the above described radioligand receptor bindingassay using cells transfected with the desired receptor in place ofcells transfected with the 5-HT_(2C) receptor subtype and using anappropriate radioligand. The binding affinities for representativecompounds of the present invention for a variety of receptors aredetermined in such assays and the compounds are found to havesurprisingly higher affinity for the 5-HT_(2C) receptor. Affinity forthe 5-HT_(2C) receptor is found to be significantly higher than forother 5-HT receptor subtypes, and notably higher than the 5-HT_(2A) and5-HT_(2B) B receptor subtypes. Preferred compounds are those with IC₅₀'s equal to or greater than 300 nM for the alpha 1 and alpha 2adrenergic receptors and equal to or greater than 500 nM for D₁ and D₂dopaminergic receptors. More preferred compounds are those with IC₅₀'sequal to or greater than 1000 nM for the alpha 1 and alpha 2 adrenergicreceptors and the D₁ and D₂ dopaminergic receptors. Still more preferredare those compounds with IC₅₀'s equal to or greater than 3000 nM for thealpha 1 and alpha 2 adrenergic receptors and the D₁ and D₂ dopaminergicreceptors.

For the above in vitro assays, exemplified compounds are assayed andfound to have either an EC₅₀ or a K; value of equal to or less than 50nM, and to have AUC 2C/2A and AUC 2C/2B ratios of greater than or equalto 2.0. Exemplified compounds are assayed and found to typically havealpha 1 and alpha 2 adrenergic receptor IC₅₀'s equal to or greater than300 nM, and D₁ and D₂ dopaminergic receptor IC₅₀'s equal to or greaterthan 500 nM.

Rat Feeding Assays

The ability of the compounds of the present invention to treat obesityis 15 demonstrated by testing in acute and chronic rat feeding assays.

Animals: Obtain male Long-Evans rats (Harlan Sprague-Dawley,Indianapolis, Ind.) that are approximately one hundred-days old and havebeen maintained on a calorie rich diet since weaning (TD 95217, 40%calories from fat; Teklad, Madison, Wis.). House the rats individuallywith a 12 h:12 h light:dark cycle (lights on from about 22:00 h to about10:00 h) and maintain rats on the same diet (TD 95217) with free accessto water, for about 1-2 weeks to acclimate the rats to the environment.Dose rats orally with vehicle (10% acacia with 0.15% saccharin in water)once daily for at least 1 day (typically 1-2 days) to acclimate the ratsto the procedures. Randomize the rats into groups so each group hassimilar mean body weights.Calorimetric Acute Feeding Assay: At approximately 8:00 h on the day ofassay, weigh each rat and transfer to individual chambers of an opencircuit calorimetry system (Oxymax, Columbus Instruments InternationalCorporation; Columbus, Ohio), with free access to food (pre-weighed) andwater, and begin measuring VO₂ and VCO₂. At approximately 10:00 h, doserats orally with vehicle or test compound, return them to theircalorimetry chambers, and continue measuring VO₂ and VCO₂ at regulartime intervals (approximately hourly). At approximately 8:00 h thefollowing day, measure rat body weight and the remaining food, assumingthe difference in weight of food is equal to the mass of food consumed.Calculate the 24 h energy expenditure (EE) and respiratory quotient (RQ)essentially as described in Chen, Y. and Heiman, M. L., Regulatory 5Peptide, 92:113-119 (2000). EE during light photoperiod is indicative ofthe resting metabolic rate and RQ is indicative of the fuel source theanimal utilizes (pure carbohydrate metabolism gives an RQ of about 1.0,pure fat metabolism gives an RQ of about 0.7, mixed carbohydrate and fatmetabolism gives intermediate values for RQ).

Calculate EE as the product of calorific value (CV) and VO₂ per bodyweight (kg); where CV=3.815+1.232*RQ, and RQ is the ratio of CO₂produced (VCO₂) to O₂ consumed (VO₂). Caloric intake is calculated as(mass of 24 h food intake in grams)×(physiological fuel value of thediet in kilocalorie/g) per kg of body weight.

Acute Feeding Assay with a selective 5-HT_(2C) receptor antagonist: Theabove calorimetric acute feeding assay is conducted with the followingmodifications. Open circuit calorimetry systems are not used and onlythe 24 h periodic food intake and body weight are measured. Three groupsof rats are used with the first group receiving a subcutaneous dose ofsaline (0.5 mL) about 15 minutes prior to the oral dose of vehicle, thesecond group receiving a subcutaneous dose of saline (0.5 mL) about 15minutes prior to the oral dose of test compound in vehicle, and thethird group receiving a subcutaneous injection of a selective 5-HT_(2C)receptor antagonist,6-chloro-5-methyl-N-{2-[(2-methylpyridin-3-yl-oxy)pyridin-5-yl]aminocarbonyl}-2,3-dihydroindole(3 mg/Kg, in 35% cyclodextrin, 0.5 mL), about 15 min. prior to the oraldose of test compound in vehicle.

Chronic Feeding Assay: At between approximately 8:00 h and 10:00 h onday one of the assay, weigh and orally dose each rat with vehicle ortest compound and return the animal to its home cage, with free accessto food (pre-weighed) and water. For each of days 2-15, at betweenapproximately 8:00 h and 10:00 h, measure rat body weight and the weightof food consumed in the last 24 h period, and administer daily oral doseof test compound or vehicle. On days −2 and 15 measure total fat massand lean mass by nuclear magnetic resonance (NMR) using an EchoMRI™system (Echo Medical Systems, Houston Tex.). (See Frank C. Tinsley,Gersh Z. Taicher, and Mark L. Heiman, “Evaluation of a New QuantitativeMagnetic Resonance (QMR) Method for Mouse Whole Body CompositionAnalysis”, Obesity Research, submitted May 1, 2003.)

Representative compounds of the present invention are tested in acuteand chronic feeding assays essentially as described above. In the acuteassays, the compounds are found to significantly reduce 24 h foodintake, which effect is blocked by pre-administration of the 5-HT_(2C)receptor antagonist. The compounds also are found to dose-dependentlyreduce RQ without significantly changing the energy expenditure duringthe light photo-period. Thus the compounds are found to reduce caloricintake and increase the proportion of fuel deriving from fatutilization, without significantly changing the resting metabolic rate.In the chronic assay, the compounds are found to significantly decreasecumulative food intake and cumulative body weight change in adose-dependent manner compared to control animals. The decrease in bodyweight is found to be due to loss of adipose tissue while lean body massis not changed.

The ability of the 5-HT_(2C) receptor agonists of the present inventionto treat obsessive/compulsive disorder is demonstrated by testing in avariety of in vivo assays as follows:

Marble Burying Assay

Marble burying in mice has been used to model anxiety disordersincluding obsessive-compulsive disorders (OCD) due to ethological studyof the behavior (e.g. Gyertyan I. “Analysis of the marble buryingresponse: Marbles serve to measure digging rather than evoke burying”,Behavioural Pharmacology 6: 24-31, (1995)) and due to thepharmacological effects of clinical standards (c.f., Njung'E K. HandleyS L. “Evaluation of marble-burying behavior as a model of anxiety”,Pharmacology, Biochemistry & Behavior. 38: 63-67, (1991)); Borsini F.,Podhoma J., and Marazziti, D. “Do animal models of anxiety predictanxiolytic effects of antidepressants?”, Psychopharmacology 163:121-141, (2002)). Thus, drugs used in the treatment of generalizedanxiety in humans (e.g. benzodiazepines) as well as compounds used totreat OCD (e.g. SSRIs like fluoxetine) decrease burying.

House experimentally-naive male, NIH Swiss mice (Harlan Sprague-Dawley,Indianapolis, Ind.) weighing between 28-35 g in groups of 12 for atleast three days prior to testing in a vivarium with 12 h light and darkcycles. Conduct experiments during the light cycle in a dimly litexperimental testing room. Dose mice with vehicle or test compound and,after a specified pretreatment interval (generally 30 min.), place eachmouse individually on a rotorod (Ugo Basile 7650) operating at a speedof 6 revolutions/min. and observe for falling. After 2 min. on therotorod, place the mice individually in a 17×28×12 cm high plastic tubwith 5 mm sawdust shavings on the floor that are covered with 20 bluemarbles (1.5 cm diameter) placed in the center. After 30 min., count thenumber of marbles buried (⅔ covered with sawdust). Assess the testcompound's effect on marble burying with Dunnett's test and the effecton rotorod performance by Fisher's exact test.

Clinically effective standard compounds suppress marble burying at dosesthat are devoid of motor-impairing effects as measured on the rotorod.The in vivo efficacy of 5HT_(2C) compounds at the 5HT_(2C) receptor isconfirmed by the prevention of effects of the 5HT_(2C) agonists onmarble burying by co-administration of the 5HT_(2C) receptor antagonist,6-chloro-5-methyl-N-{2-[(2-methylpyridin-3-yl-oxy)pyridin-5-yl]aminocarbonyl}-2,3-dihydroindole.

Representative compounds of the present invention are assayed in themarble burying assay essentially as described and are surprisingly foundto reduce burying behavior in the test mice. The reduction of buryingbehavior is found to be blocked by co-administration of the 5-HT_(2C)antagonist. In contrast to the compounds of the present invention, theanxiolytic compound chlordiazepoxide and the antipsychotic compoundchlorpromazine decrease marble burying only at doses that also disruptrotorod performance.

Nestlet Shredding

Mice naturally will construct nests of material available in theirliving environment. Since this behavior is obsessive in nature, it hasbeen used to model OCD (Xia Li, Denise Morrow and Jeffrey M. Witkin,“Decreases in nestlet shredding of mice by serotonin uptake inhibitors:comparison with marble burying”, Psychopharmacology, submitted Jul. 14,2003). House experimentally-naïve male, NIH Swiss mice (HarlanSprague-Dawley, Indianapolis, Ind.) weighing between 28-35 g in groupsof 12 for at least three days prior to testing in a vivarium with a 12 hlight/dark cycle. Conduct experiments during the light cycle in anexperimental room with normal overhead fluorescent lighting. Dose micewith vehicle or test compound and after a specified pretreatmentinterval (generally 30 min.), place the mice individually in a 17×28×12cm high plastic tub with about 5 mm sawdust shavings on the floor alongwith a pre-weighed multi-ply gauze pad (51 mm square). After 30 min.,weigh the remainder of the gauze pad not removed by the mouse. Determinethe weight of the gauze used for nestlet construction by subtraction.Compare the results for test compound treated mice to the results forvehicle control treated mice with Dunnett's test.

Clinically effective OCD treatment standard compounds suppress nestletshredding at doses that are devoid of motor-impairing effects asmeasured by the rotorod test. The ill vivo efficacy of 5HT_(2C)compounds at the 5HT_(2C) receptor is confirmed by the prevention ofeffects of the 5HT_(2C) agonists on nestlet shredding byco-administration of the 5HT_(2C) receptor antagonist,6-chloro-5-methyl-N-{2-[(2-methylpyridin-3-yl-oxy)pyridin-5-yl]aminocarbonyl}-2,3-dihydroindole.Representative compounds of the present invention are assayedessentially as described above and are surprisingly found to suppressnestlet shredding at doses that are devoid of motor-impairing effects asmeasured by the rotorod test.

In contrast to the compounds of the present invention, the anxiolyticchlordiazepoxide and the psychomotor stimulant d-amphetamine decreasesnestlet shredding only at doses that produce motoric side effects(depression or stimulation, respectively).

Schedule-Induced Polydipsia

Food-deprived rats exposed to intermittent presentations of food willdrink amounts of water that are far in excess of their normal dailyintake and in excess of their intake when given all of their food at onetime (Falk J L. “Production of polydipsia in normal rats by anintermittent food schedule”, Science 133: 195-196, (1961)). Thisexcessive behavior is persistent and has been used to model OCD.

Maintain Wistar rats on a food restricted diet (to maintain 85% freefeeding weight), but with free access to water. Train the rats in abehavioral testing chamber to press a lever to receive a food pelletunder a fixed interval schedule, such that the rats are rewarded with a45 mg food pellet the first time they press a lever after a 120 secondinterval has elapsed. The fixed interval is then reset to 120 secondsand the process repeated. Thus, during a 90 min. test session, the ratscan earn a maximum of 45 pellets. The behavioral chamber is alsoequipped with a water bottle that is weighed before and after thesession to determine the amount of water consumed.

Administer test compounds on Tuesdays and Fridays. Determine control dayperformances on Thursdays. Administer compounds either orally at 60 min.before the beginning of a test session, or subcutaneously at 20 min.before the beginning of a test session. Compare the rates of leverpressing and water consumption for each animal's performance duringsessions after test compound treatment with that animal's performanceduring control sessions, expressed as a percent of the control rate.Average the individual percent of control rates for each dose andcalculate the standard error of the mean.

Clinically effective OCD treatment standard compounds (e.g.chlomipramine, fluoxetine) suppress schedule-induced polydipsia withoutproducing notable changes in motor patterns, food intake, or behaviorthe following day. The in vivo efficacy of 5HT_(2C) compounds at the5HT_(2C) receptor is confirmed by the prevention of effects of the5HT_(2C) agonists on excessive drinking by co-administration of the5HT_(2C) receptor antagonist,6-chloro-5-methyl-N-{2-[(2-methylpyridin-3-yl-oxy)pyridin-5-yl]aminocarbonyl}-2,3-dihydroindole.

Representative compounds of the present invention are assayed in theschedule-induced polydipsia assay essentially as described above and aresurprisingly found to suppress schedule-induced polydipsia withoutproducing notable changes in motor patterns, food intake, or behaviorthe following day. The behavior suppression is blocked byco-administration of the 5-HT_(2C) antagonist.

In contrast to the compounds of the present invention, the psychomotorstimulant d-amphetamine decreases excessive drinking only atbehaviorally stimulating doses and these effects are not prevented bythe 5HT_(2C) receptor antagonist.

While it is possible to administer compounds employed in the methods ofthis invention directly without any formulation, the compounds areusually administered in the form of pharmaceutical compositionscomprising a pharmaceutically acceptable excipient and at least onecompound of Formula I or a pharmaceutically acceptable salt thereof.

These compositions can be administered by a variety of routes includingoral, rectal, transdermal, subcutaneous, intravenous, intramuscular, andintranasal. The compounds employed in the methods of this invention areeffective as both injectable and oral compositions. Such compositionsare prepared in a manner well known in the pharmaceutical art. See, e.g.REMINGTON'S PHARMACEUTICAL SCIENCES, (16th ed. 1980).

In making the compositions employed in the present invention the activeingredient is usually mixed with at least one excipient, diluted by atleast one excipient, or enclosed within such a carrier which can be inthe form of a capsule, sachet, paper or other container. When theexcipient serves as a diluent, it can be a solid, semi-solid, or liquidmaterial, which acts as a vehicle, carrier or medium for the activeingredient. Thus, the compositions can be in the form of tablets, pills,powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions,solutions, syrups, aerosols (as a solid or in a liquid medium),ointments containing for example up to 10% by weight of the activecompound, soft and hard gelatin capsules, suppositories, sterileinjectable solutions, and sterile packaged powders.

In preparing a formulation, it may be necessary to mill the compound toprovide the appropriate particle size prior to combining with the otheringredients. If the active compound is substantially insoluble, itordinarily is milled to a particle size of less than 200 mesh. If theactive compound is substantially water soluble, the particle size isnormally adjusted by milling to provide a substantially uniformdistribution in the formulation, e.g. about 40 mesh.

Some examples of suitable excipients include lactose, dextrose, sucrose,sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates,tragacanth, gelatin, calcium silicate, microcrystalline cellulose,polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. Theformulations can additionally include: lubricating agents such as talc,magnesium stearate, and mineral oil; wetting agents; emulsifying andsuspending agents; preserving agents such as methyl- andpropylhydroxybenzoates; sweetening agents; and flavoring agents. Thecompositions of the invention can be formulated so as to provide quick,sustained or delayed release of the active ingredient afteradministration to the patient by employing procedures known in the art.

The compositions are preferably formulated in a unit dosage form, eachdosage containing from about 0.05 to about 100 mg, more usually about1.0 to about 30 mg, of the active ingredient. The term “unit dosageform” refers to physically discrete units suitable as unitary dosagesfor human subjects and other mammals, each unit containing apredetermined quantity of active material calculated to produce thedesired therapeutic effect, in association with a suitablepharmaceutical excipient.

The compounds are generally effective over a wide dosage range. Forexamples, dosages per day normally fall within the range of about 0.01to about 30 mg/kg. In the treatment of adult humans, the range of about0.1 to about 15 mg/kg/day, in single or divided dose, is especiallypreferred. However, it will be understood that the amount of thecompound actually administered will be determined by a physician, in thelight of the relevant circumstances, including the condition to betreated, the chosen route of administration, the actual compound orcompounds administered, the age, weight, and response of the individualpatient, and the severity of the patient's symptoms, and therefore theabove dosage ranges are not intended to limit the scope of the inventionin any way. In some instances dosage levels below the lower limit of theaforesaid range may be more than adequate, while in other cases stilllarger doses may be employed.

Another preferred formulation employed in the methods of the presentinvention employs transdermal delivery devices (“patches”). Suchtransdermal patches may be used to provide continuous or discontinuousinfusion of the compounds of the present invention in controlledamounts. The construction and use of transdermal patches for thedelivery of pharmaceutical agents is well known in the art. See, e.g.,U.S. Pat. No. 5,023,252, issued Jun. 11, 1991, herein incorporated byreference. Such patches may be constructed for continuous, pulsatile, oron demand delivery of pharmaceutical agents.

Under some circumstances, it will be desirable or necessary to introducethe pharmaceutical composition to the brain, either directly orindirectly. Direct techniques usually involve placement of a drugdelivery catheter into the host's ventricular system to bypass theblood-brain barrier. One such implantable delivery system, used for thetransport of biological factors to specific anatomical regions of thebody, is described in U.S. Pat. No. 5,011,472, issued Apr. 30, 1991,which is herein incorporated by reference.

Indirect techniques, which are generally preferred, usually involveformulating the compositions to provide for drug latentiation by theconversion of hydrophilic drugs into lipid-soluble drugs or prodrugs.Latentiation is generally achieved through blocking of the hydroxy,carbonyl, sulfate, and primary amine groups present on the drug torender the drug more lipid soluble and amenable to transportation acrossthe blood-brain barrier. Alternatively, the delivery of hydrophilicdrugs may be enhanced by intra-arterial infusion of hypertonic solutionswhich can transiently open the blood-brain barrier.

The type of formulation employed for the administration of the compoundsemployed in the methods of the present invention may be dictated by theparticular compound employed, the type of pharmacokinetic profiledesired from the route of administration, and the state of the patient.
